Title: Moisture meter
Inventor: MURAMATSU KENGO
IPC: F26B9/06
Filed: 1999-03-05
Abstract: PROBLEM TO BE SOLVED: To accurately measure the water content of grain from the resistance value of crushed grain. SOLUTION: Grain is crushed by an electrode roller and the resistance value R of crushed grain is continuously measured and the water content of grain is calculated on the basis of the resistance value R lower than a threshold value THD. Herein, the rotational speed of the electrode roller is measured and, when the continuing period of the resistance value R lower than the threshold value THD is longer than a predetermined time, the continuing period is cut off at a predetermined discrimination time interval Tc proportional to the rotational speed of the electrode roller and the resistance value R generated within the cut off period is set to the resistance value of one sample to calculate water content.  When the continuing period of the resistance value R lower than the threshold value THD is shorter than the discrimination time interval Tc, on condition that the continuing period is longer than a predetermined time limit value Tg shorter than the discrimination value generated during the continuing period is set to the resistance value of one sample to calculate water content. By this constitution, the water content of grain can be accurately calculated without receiving the influence of the rotational speed of the electrode roller.

Title: Display apparatus for vehicle
Inventor: TERAOKA HIROKI
IPC: G06F3/038
Filed: 1989-03-10
Abstract: PURPOSE:To allow a track ball to always perform accurate input operation without receiving the effect of the vibration of a vehicle by permitting the control of the movement of a mark during a period when the detection signal for detecting the operation state of the track ball is generated. CONSTITUTION:When the position of a mark to the data displayed by a display means 1 is improper, an operation means 2 generates an operation signal when a track ball 2a is set to an operative state and a detection means 3 generates a detection signal and a control means 4 moves the mark under the generation of the detection signal. When the operation of the track ball 2a is stopped, the control means 4 stops the movement of the mark at the time of the extinction of the detection signal. As mentioned above, since the movement control of the mark due to the control means 4 is permitted only during a period when the detection means 3 generates the detection signal, even when the operation signal is generated from the operation means 2 by mistake, the control means 4 performs no movement control of the mark.

Title: Detecting method for reference mark position by electron beam exposure
Inventor: IWATATE KAZUMI
IPC: G01B15/00
Filed: 1979-05-16
Abstract: PURPOSE: To shorten the time of mark detection by shortening the scanning distance of an electron beam by stopping the scanning of the electron beam while stopping the counting of a counter when a mark signal is generated in the scanning of the electron beam.  
     CONSTITUTION: In the method of detecting a reference mark position on a sample surface through the scanning of an electron beam, electron beam generator 6 generates electron beam 7 on the generation of a scan start instruction from computer 1 to timing control circuit 5. Since a signal corresponding to the mark signal is sent from detecting circuit 17 to gate circuit 18 and timing control circuit 5, the transmission of the mark signal by scanning mark 14 closes gate circuit 18, and consequently while counter 10 stops counting, the scanning of electron beam 7 is also stopped by a signal from timing control circuit 5, so that the time of mark detection will be shortened.

Title: Band switching circuit of tuner
Inventor: MOTOYAMA IKUO
IPC: H03J5/24
Filed: 1979-05-16
Abstract: PURPOSE:To improve the isolation between the UHF and VHF parts in a simple constitution, by connecting between the mixture terminal and the cathode terminal of the high frequency switch diode via the resistance. CONSTITUTION:Mixer terminal 20 is connected to the cathode terminal of high frequency switch diode 11 via resistance 31. Thus diode 11 of the input circuit receives the backward bias at all times to secure the OFF mode at the time of receiving the VHF low band as well as the UHF and by the +B voltage supplied to the mixer terminal. Accordingly, the low band receiving mode is secured by supplying the +B voltage to terminal 19, and no disturbance due to the nonlinear distortion of diode 11 is caused in the UHF receiving mode under which the +B voltage is supplied to terminal 19. On the other hand, the +B voltage is applied to terminal 21 at the time of the receiving the VHF high band to give the forward bias to diode 11. In such way, the isolation can be improved between the UHF and VHF parts in a simple constitution.

IPC: H04N9/04
Filed: 1981-04-21
Abstract: PURPOSE:To obtain a color television image pickup device which achieves secure color separation by using a color filter which removes long wave light rays. CONSTITUTION:Light passed through a photographic lens 1 is imaged on the photosensitive part of a CCD4 through a color filter 2. This color filter 2 removes almost all of long-wavelength components above 650nm, so a color filter array 3 and the CCD4 are used in combination to separate a signal of each picture element securely into signal components free of color mixture. The output signal of the CCD4 is applied to a color separating circuit 5, where it is separated into three primary color signals of red, blue and green and a luminance signal before being applied to a signal processing circuit 6. Then, signal processing such as gamma correction and white clipping is carried out and a trailing color encoder 7 obtains an NTSC signal.

Title: Portable electronic device provided with speaker enclosure with opening
Inventor: SUKOTSUTO NOOBURU HITSUKUMAN
IPC: H04R1/02
Filed: 1996-03-15
Abstract: PROBLEM TO BE SOLVED: To increase the maximum input power of a speaker housed in a small case body by improving the acoustic characteristics of the case body. SOLUTION: In addition to a first aperture 12 for leading out sound from the front surface of the speaker 150, a route (first chamber 210 → second chamber 220 → second aperture 110) for leading out the sound from the back surface of the speaker to the front surface of the case body is provided. The respective kinds of the dimensions of the route are determined so as to turn the sound generated from the first and second apertures to the almost same phase with each other. Thus, since the amplitude of a speaker diaphragm at the resonance frequency of the speaker becomes extremely small, destruction by the amplitude of the diaphragm exceeding an allowable limit at the time of supplying large power to the speaker is prevented.

Title: Pressure control valve
Inventor: TAKAYAMA TERUO
IPC: F16K31/06
Filed: 1982-04-08
Abstract: PURPOSE:To eliminate the necessity for using a conventional fixed pressure valve and form a pressure control valve to small size at a low price, by constituting the pressure control valve, which controls a level of negative pressure supplied to an exhaust gas recirculation valve of an engine, in such a manner that a one-way operating valve is built in the bottom part of a plunger in a solenoid mechanism part. CONSTITUTION:When an electric current is not conducted to a coil 16, a seal member 26 closes an opening part 8 of an input passage 3, and negative pressure is not supplied to an output passage 12. Then if the current conducted to the coil 16 becomes at least a prescribed value, the member 26 is moved upward through a plunger 18 to open the part 8. Here if input negative pressure is smaller than prescribed negative pressure, a valve body 25 in a one-way operating valve 20 is moved upward, and output negative pressure is decreased by the atmosphere inflowing from a leak passage 13. While if input negative pressure increases larger than prescribed negative pressure, said body 25 is moved downward to introduce the atmosphere through the passage 13 and through holes 17a, 18a, and the negative pressure decreases.
